In the world’s most dynamic capital market, trading doesn’t happen in a vacuum.

But who exactly is in charge—and what do they regulate?
Understanding who regulates trading in the U.S. isn’t just for compliance officers. Whether you're a retail trader, institutional investor, broker-dealer, or fintech founder, regulatory clarity is essential for risk management, legal compliance, and strategic execution. This guide breaks down the major U.S. trading regulators, their roles, 2025 updates, common enforcement triggers, and what it means for you.

Why This Matters: Real Consequences for Traders and Firms
